Because these are already the lowest prices possible, the additional incentives usually available under "Frequent Flyer" program do not apply to this item.
Herbie's Iso-Cup is formulated specifically to address vibration problems unique to vacuum tube amplifiers, such as transformer vibration, tube sensitivity, and proximity of capacitors to chassis vibration, while bringing out more of the amplifiers' inherent sonic potential and dynamics. Although Iso-Cups are most effective with open-chassis tube amplifiers, they also provide superb isolation/decoupling for most other audio and video components.
Iso-Cup: Pillowy soft, platinum-cured silicone reduces glare, fuzz, sibilance, and artificial harshness caused by micro-vibrations. Frosted clear blends aesthetically with any audio/video system.
Lampblack Ball: Maintains a linear frequency response with full-bodied dynamics and texture; deeply extended, punctual bass; intricate highs; smooth dynamics with plenty of punch and detail; superb imaging and soundstage; perfect tone/timbre. Provides microdynamic speed that Iso-Cup alone would not achieve. Iso-Cup holds hard Lampblack ball in place; ball does not roll.
Hi-End Base: Optional stainless steel base features a broad concave depression filled flat with silicone gel to absorb downward pressures exerted by the Iso-Cup ball and prevent any potential counter-vibration within the Iso-Cup body. Achieves a highly organic musical result.
Combination of Iso-Cup, Lampblack Ball and Hi-End base brings tube amplifier performance to an elite standard at the top of the hi-end footers class.
.Recommended for tube amplifiers weighing from 14 to 80 pounds (6-36kg), up to 100 pounds with four Iso-Cups (for amps heavier than 100 pounds, use more Iso-Cups or Extra-Firm Big Tall Tenderfeet).
Dimensions, Iso-Cup, ball and base: 1.5" wide by.1.55" tall.
(without Hi-End Base: 1.4" tall)
